Abstract

An electrode manufacturing apparatus (1) includes: an applier (5) configured to apply a liquid composition (24) to form an insulating layer (21) onto an electrode base (9) or a functional layer (12) on the electrode base (9); a controller (40) configured to control the applier (5); and a surface detector (8) configured to detect a surface condition of the liquid composition (24) or the insulating layer (21) on the electrode base (9) or the functional layer (12), wherein the controller (40) controls the applier (5) based on the surface condition of the liquid composition (24) or the insulating layer (21) detected by the surface detector (8).
